Predictive factors for relapse in corticosteroid-treated patients with chronic eosinophilic pneumonia

BackgroundChronic eosinophilic pneumonia (CEP) is an idiopathic disorder characterised by an abnormal and marked accumulation of eosinophils in the interstitium and alveolar spaces of the lungs. Systemic corticosteroid (CS) therapy leads to marked improvement. However, relapse is common in the clinical course, and the predictive factors for relapse of CEP are not well known. This study aimed to investigate predictive factors for relapse in CS-treated cases of CEP.MethodsWe identified consecutive patients with CEP at our institution between 1999 and 2019. We retrospectively reviewed 36 CS-treated patients with CEP who underwent bronchoalveolar lavage (BAL) and high-resolution computed tomography (CT) at diagnosis. We examined relapse at least 1 year after the initiation of CS treatment. Statistical analysis included univariate and multivariate Cox proportional hazard regression analyses; P<0.05 was considered statistically significant.ResultsThe median (interquartile range) age at diagnosis was 59.5 years (47.8–70.0 years). This study included 13 men and 23 women. Twenty-five patients (69.4%) were never smokers and 15 (41.7%) had asthma. The peripheral blood eosinophil percentage was 35.0% (15.6–55.8%), and the BAL eosinophil percentage was 40.8% (10.7–68.5%). The median serum surfactant protein-D (SP-D) level was 135 ng/mL (82.2–176.7 ng/mL). High-resolution CT revealed centrilobular opacities in 23 patients (63.9%). Relapse of CEP was observed in 20 patients (55.6%). Higher serum SP-D levels and the presence of centrilobular opacities on high-resolution CT were significant predictors of relapse in multivariate Cox proportional hazard regression analysis (P=0.017 and P=0.028, respectively). Additionally, we devised a relapse prediction model for CS-treated CEP using two categorical parameters: the presence of centrilobular opacities and serum levels of SP-D (>135/≤135 ng/mL). Based on these parameters, cases were scored 2, 1, or 0. Patients with a score of 2 experienced relapses earlier than those with scores of 1 and 0 (log-rank test; P=0.006, P=0.003, respectively).ConclusionsCentrilobular opacities on high-resolution CT and higher serum SP-D levels at diagnosis may be predictive factors for relapse in CS-treated patients with CEP.     

Clinicopathological differences between acute and chronic eosinophilic pneumonia

OBJECTIVE: Considerable confusion exists regarding the proper classification of idiopathic eosinophilic pneumonia (IEP). Furthermore, there are no reports describing the clinicopathological differences between the various forms of eosinophilic pneumonias. METHODOLOGY: The histological findings in acute eosinophilic pneumonia (AEP) and chronic eosinophilic pneumonia (CEP) were examined and the clinical and radiological features were contrasted with them. RESULTS: Radiologically, ground glass opacity and interlobular septal thickening were characteristic of the AEP cases, while air space consolidation was seen in all CEP cases. Histologically, interstitial oedema and fibrin deposition were prominent in the AEP cases. Type II cells were detached from the alveolar walls, although the basal lamina was predominantly intact. In CEP, in addition to cellular infiltration, there was prominent intraluminal fibrosis. Disruption of the basal lamina was observed and nests of intraluminal fibrosis were directly adjacent and connected to the alveolar walls. CONCLUSIONS: An essential histological difference between AEP and CEP is the severity of basal lamina damage and the amount of subsequent intraluminal fibrosis. In AEP particularly, these findings explain the radiographical findings, as well as the rapid and complete improvement noted in such cases.     

Tracheobronchial lesions in eosinophilic pneumonia

BackgroundEosinophilic pneumonia (EP) is characterized by eosinophil infiltration in the lung parenchyma. However, tracheobronchial lesions associated with the disease have been poorly described. To clarify the frequency and characteristics of cases with tracheobronchial lesions in EP, we performed a retrospective review of EP patients.MethodsWe included 36 EP cases seen from January 2004 to December 2007 at the Kinki-Chuo Chest Medical Center. The incidence of tracheobronchial nodules and associated clinical features were analyzed.ResultsOf these 36 patients, 29 had chronic eosinophilic pneumonia (CEP); 1, acute EP; 3, drug-induced EP; 2, allergic bronchopulmonary aspergillosis; and 1, parasite-related EP. Only 2 of the 29 CEP cases had tracheobronchial lesions. For both of these cases, bronchoscopy revealed multiple whitish nodules on the tracheobronchial mucosa. The associated histopathological findings revealed squamous metaplasia and eosinophil infiltration in the subepithelial region. In both cases, the nodules disappeared after steroid therapy. The prevalence of tracheobronchial lesions was 6.9% in CEP patients and 5.6% in EP patients overall. EP patients were divided into 3 groups: CEP with nodules (n=2), CEP without nodules (n=27), and other EP (n=7). We found that the CEP with nodules group showed a relatively higher incidence of respiratory symptoms, higher white blood cell (WBC) count, and higher levels of peripheral and bronchoalveolar eosinophilia than the other groups.ConclusionsTracheobronchial nodules represent rare observations within the EP population, which are likely to reflect a severe disease condition.     

Bronchial involvement in chronic eosinophilic pneumonia: a case report

Chronic eosinophilic pneumonia (CEP) is an idiopathic chronic condition characterized by alveolar filling with mixed inflammatory infiltrate consisting largely of eosinophils. On CT, it is usually observed as consolidation, often peripheral and patchy in distribution, with upper lobe dominance. Airway involvement in CEP is very rare. We report on a case of bronchial involvement in CEP.     

Chronic eosinophilic pneumonia associated with an initiation of rheumatoid arthritis

Although peripheral blood eosinophilia is observed in patients with active inflammatory rheumatoid arthritis (RA), RA is not a recognised cause of pulmonary eosinophilia. We describe a 55-year-old woman affected by chronic eosinophilic pneumonia (CEP) concomitantly with an initiation of RA. Both diseases responded rapidly and completely to high-dose corticosteroid therapy. In this patient, the initiation of RA and CEP was directly related, implying a common pathogenetic link between the two diseases.
